+# OpenTofu plugin
+
+Plugin for OpenTofu, a fork of Terraform that is open-source, community-driven, and managed by the Linux Foundation. It adds
+completion for `tofu` command, as well as aliases and a prompt function.
+
+To use it, add `opentofu` to the plugins array of your `~/.zshrc` file:
+
+```shell
+plugins=(... opentofu)
+```
+
+## Requirements
+
+- [OpenTofu](https://opentofu.org/)
+
+## Aliases
+
+| Alias | Command         |
+| ----- | --------------- |
+| `tt`  | `tofu`          |
+| `tta` | `tofu apply`    |
+| `ttc` | `tofu console`  |
+| `ttd` | `tofu destroy`  |
+| `ttf` | `tofu fmt`      |
+| `tti` | `tofu init`     |
+| `tto` | `tofu output`   |
+| `ttp` | `tofu plan`     |
+| `ttv` | `tofu validate` |
+| `tts` | `tofu state`    |
+| `ttsh`| `tofu show`     |
+| `ttr` | `tofu refresh`  |
+| `ttt` | `tofu test`     |
+| `ttws`| `tofu workspace`|
+
+
+## Prompt functions
+
+- `tofu_prompt_info`: shows the current workspace when in an OpenTofu project directory.
+
+- `tofu_version_prompt_info`: shows the current version of the `tofu` commmand.
+
+To use them, add them to a `PROMPT` variable in your theme or `.zshrc` file:
+
+```sh
+PROMPT='$(tofu_prompt_info)'
+RPROMPT='$(tofu_version_prompt_info)'
+```
+
+You can also specify the PREFIX and SUFFIX strings for both functions, with the following variables:
+
+```sh
+# for tofu_prompt_info
+ZSH_THEME_TOFU_PROMPT_PREFIX="%{$fg[white]%}"
+ZSH_THEME_TOFU_PROMPT_SUFFIX="%{$reset_color%}"
+# for tofu_version_prompt_info
+ZSH_THEME_TOFU_VERSION_PROMPT_PREFIX="%{$fg[white]%}"
+ZSH_THEME_TOFU_VERSION_PROMPT_SUFFIX="%{$reset_color%}"
+```
